This is a fence idea we are trying out for camping this year. The corgis can jump it but I think we have convinced them it is not ok. We used to travel by boat a lot(prior to the recession!) and taught them not to bark at everything they see go bye. You really can't do that in Marinas. So now that we have switched to camping they have been very well behaved. They love camping especially going with us everywhere and meeting lots of new people!
